A RARE 16th-century seal connected to the royal House of Stewart (or Stuart as the name later became) is being auctioned live online by Edinburgh-headquartered Lyon & Turnbull this Tuesday.

The Stewart rule spanned nine monarchs, beginning in Scotland in 1371 and ending in 1714, by which time it also encompassed England and Ireland.

The James Stewart, Commendator of Melrose Seal has remarkably survived nearly 500 years and would have been made for one of King James V’s seven illegitimate sons, four of whom were called James/John.

The title demonstrates recognition by their father (Mary, Queen of Scots would become his only surviving legitimate child) despite being born out of wedlock and not receiving royal titles.

James Stewart’s position as Commendator of the Abbeys of both Kelso and Melrose made him very influential.

By giving James Stewart the title of Commendator, the king not only instilled a level of power in his son, the role also served to protect the king’s interest in areas bordering England.

The last time this particular seal, which relates to Melrose Abbey, was seen in public was in 1901. It was displayed during the Glasgow International Exhibition at Kelvingrove Park which attracted more than 11.5 million visitors.

Since that time, the seal, one of a collection up for sale, has remained in the same family.

Colin Fraser, consultant specialist at Lyon & Turnbull, said: “Such early and historical survivals are rare for Scotland. Something so personal to the owner and, in this case an owner with such power and close connection to the Royal Stewart household, is remarkable. While early seals do survive, the vast majority are in institutional collections so never become available to collectors. This is a very unusual opportunity for someone to own an amazing piece of history.”

Interest in this rare item is expected to be high, with bidding starting at £1000.
